The technique performed good repeatability (RSD= 7.28–9.53%) and good reproducibility (RSD=7.07–15.10%). The precisions are accepted according to the Association of Official Analytical Chemists (AOAC) standard (RSD repeatability <11% and RSD reproducibility <16% at a concentration of 1 µg mL<sup>-1</sup>). The method offered high operational stability up to 18 measurements (RSD=4.6%). The technique performs acceptable results with low random error in determining Pb(II).</span></p> |
